Description Chris Dearborn 2014-07-16 18:03:28 UTC 
Description of problem:
When Glance is configured to use rbd as a backend, Ceph requires show_image_direct_url to be set to True to allow copy-on-write clone of an image.
See: http://ceph.com/docs/next/rbd/rbd-openstack/

This bug is to modify astapor (controller_common.pp and glance.pp) so that if the glance backend is "rbd" , then it will pass True for show_image_direct.

Taken from http://ceph.com/docs/next/rbd/rbd-openstack/:
Note that this exposes the back end location via Glance’s API, so the endpoint with this option enabled should not be publicly accessible

Not really sure.  I'm going by the documentation on the Ceph web site (the link has since changed to this: http://docs.ceph.com/docs/master/rbd/rbd-openstack/)

Closing list of bugs for RHEL OSP Installer since its support cycle has already ended [0]. If there is some bug closed by mistake, feel free to re-open.

For new deployments, please, use RHOSP director (starting with version 7).
